Nous non parlons pas bouquet de Francais ici (switching to English before I embarrass myself), but:

I am not a sqlplus expert. There may be a way to put a sql statement on the command line. I am sure there is a way to have sqlplus execute a sql file. You could write a little script that calls the procedure, save it to a file, and then call sqlplus to execute the file.

Of course, the real way to do this is to open a Perl DBI session and execute the procedure from inside your script.
